A rectovaginal fistula is a medical condition where there is a fistula or abnormal connection between the rectum and the vagina. Passage of gas, stool or pus from the vagina. Foul-smelling vaginal discharge. Recurrent vaginal or urinary tract infections. Irritation or pain in the vulva, vagina and the area between the vagina and anus (perineum) Pain during sexual intercourse.
After diagnosing rectovaginal fistula, it is best to wait for around 3 months to allow the inflammation to subside. For low fistulae, a vaginal approach is best, while an abdominal repair would be necessary for a high fistula at the posterior fornix. A circular incision is made around the fistula and vagina is separated from the underlying rectum with a sharp circumferential dissection. The entire fistulous tract, along with a small rim of rectal mucosa is incised. The rectal wall is then closed extramucosally.
The median follow-up period was 25 months, and the median age of the patients was 44 years old (range, 25–70 years old). The mean operative time was 130 min (range, 90–150 min), and the hospital stay was 5 days (range, 3–8 days). One patient experienced recurrence. This patient underwent reoperation with TEM and experienced re-recurrence. Two patients had minor complications (hematoma of the septum and abscess of the septum), which were treated with medical therapy. For two patients, a moderate sphincter hypotonia was recorded.
